CONCRETE MOLD.

Application led August 1, 1922.

Be it known that I. )inni 'i`i'siiiiiwiC:/.. a citizen of the l'nitedStates ot' America, residing at Rothschild. in the count-y of Marathonand State oi' 'isconsin. have invented certain new and usefulimprovements in (fom-rete Molds. oi which the followingr is aspecification.

'l`his invention relates to certain new and usei'ul improvements inconcrete molds and has particular re ference to that type of mold formedoi' collapsible sections Jor molding lloors. walls or the like whereinreinforcing elements. `such as l-beams are imhedded in the concrete.

'lhe primary object ot' the invention resides in the provision of aconcrete mold wherein reinforcing -heam sections are rig idl)v supportedin spaced relation with arch forms interposed between said -beam formolding a reinforced floor or the like.

With 'the above general ohjects in view and others that will appearasthe nature of the invention is better understood. the same consists ofthe novel t'orin. combination and arrangement of parts hereinafter more{ull}I descrihed, shown in the accompanying drawing ind claimed.

in the drawing. wherein like reference characters designatecorresponding parts throughout the several views,

Figure 1 is a fragmentary cross sectional view ot' a molded floorsection showing the mold clamping blocks engaging the reinforcingI-beam. the intermediately positioned arch membeis or forms' and theconcretebodv supported in the mold,

Figure 2 is a horizontal sec-tional view talcenon line H -Ii of Fig. 1showing the clamping blocks ot' the mold,

`Figure 3 is a vertical cross sectional view taken on line iI-HI of Fig.1 showing a part of the arch form support-ing the concrete filling withthe arch torni supported on the clamping blocks, and

Figure l is a. top plan view ot a pair ot' clamping lilocks shown intheir separa-ted extended position with a reinforcingr -beam positionedthereon and illustrated b v dot-ted lines. i

The present invention being' especially designed for molding flat bodiesor plain surfaces. such as ioors. walls or ceilings ot' con-v cretehaving reinforcing elements imbedded therein. such as fheams, the deviceembodies in detail. a plurality of clamping` bloclts ar Serial N0.578,916.

vranged in pairs. each .pair including a subby the outer e'nd of eachclamping block l for engagement with the adjacent edges of the lowerflanges of reinforcing Lbeams imbedded in the concrete.

In the molding of a wall or similar body, a plurality of pairs ofclamping blocks 1 are arranged in spaced rows and in spaced relation.the clamping blocks being separated to assume the position illustratedin Fig. l. Reinforcing Lbeanis l() have the lower flanges 11 contactingthe legs 3 and l of the clamping blocks and said blocks are moved towardeach other to` assume the position shown iii/Fig. 2, permitted by l'thebolt and slot connection between the clamping blocks and so retained b vthe bolt and nuts 7 and 8. rched forms 12 of thedesircd configuration,preferably of substantially U- shaped in cross section having side legs13 are supported at their lower ends on the ad- 'jacent edges of thespaced rows of clamps.

the side walls 13 of thel arched forni beingl cnt away as at 14 toprovide clearances for the clamping lugs 9 as clearly shown in Figs. 1and 3. Concrete or other material 15 is then poured into theA molds.covering the ached Aforms 12 with the I-beams 10 irnbedded therein. Withthe clamping blocks so positioned. binding screws 16 passing upwardlythrough the clamping blocks engage the lower faces of the danges 11 ofthe beains for securely clamping the saine in the blocks 1. After theconcrete has set and hardened. the clamping blocks 1 are separated tothe position shown in Fig. 4 to dis engage the clamping lugs 9 `trom thelower flanges 11 of the -beam. at which time such clamping blocks may berea'dilyremoved from engagement therewith. The arched forms 12 are thenremoved from the concrete body 15 in any desired manner leaving lll) themolded lconcrete l with the reinforcingl Lbeams l0 imbedded therein. ltwill be noted that the clamping blocks l directly engage the inforcinglll-beams and the arched forms 12 in setting up the molds for receivingthe concrete filling 15 and said clamping blocks and arched forms areremoved from the concrete body after the same has been allowed to setand harden.

Vhile there is herein shown and described the preferred embodiment ofthe present invention, it is nevertheless to be understood that minorchanges may-be made therein Without departing from the spirit and scopeof the invention as claimed. What l claim as new is 1. In a concretemold, a plurality of clamping blocks arranged in spaced relation and inspaced rows, each clamping block in' cluding separable members, meanscarried reaaeeo thereby for engaging the adjacent side edges of theflanges of reinforcing -beams, arch forms of inverted substantialU-shape having the opposite edges thereof supported on the opposed edgesol adjacent rows of clamping blocks, and binding members carried by theclamping blocks for engaging the lower faces of the reinforcing Lbeam.

2 ln a concrete mold7 a plurality of clamping blocks arranged in spacedrelation and in spaced rows, each clamping blocl; in-

cluding a body portion having opposed cnt away faces to form overlappingleg members, bolt and slot connections between said leg members topermit relative sliding movement thereof, and an inwardly directedclamping lug hook carried by the outer end of each member of theclamping block.

ln testimony whereof l aiiix my signature.
